If you’ve written a book full of Mac tips, as I have, it’s inevitable people ask what my favourite tips are. So here they are, for one-time only—the top 10 tricks I use every day. They’re not all barnstormers, and they’re not guaranteed to be mind-blowing. They’re just the little things I do to make life easier and more efficient when I’m using my Mac.

We’ve been anticipating Apple’s revolutionary new television set, dubbed the “iTV,” since Steve Jobs revealed he had “finally cracked” the TV to his biographer, Walter Isaacson. What we’re most excited about is its rumored Siri integration, but you don’t need to wait until Apple’s set is launched to get a Siri-controlled TV — it’s already here.

Following its debut on the iPhone 4S back in October, it seems every iOS user wants to get their hands on Siri. A number of developers have attempted to port the feature to older devices, but because it needs to talk to Apple’s servers to function properly, they’ve had little success. Until now!

A fully functional (and possibly illegal) version of Siri has made its way to the jailbroken iPhone 4 via Cydia.

We all gave up the ability to jailbreak and tether our iPhones when we updated them to iOS 4 or purchased an iPhone 4. Hackers have been teasing us that an iOS 4 jailbreak is imminent, but now you don’t have to wait for them or the jailbreak to have tethering again. You can have tethering on your iPhone now — using an open source project hosted on GitHub called iProxy.
